Answer:
The bill will be $26070.
Step-by-step explanation:
Your base plan costs you $30 a month
And each text sent or received is only 12 cents or $0.12.
Let the messages sent be = x
So, cost for messages become =
Let total bill cost be = y
Now, total bill will comprise of monthly plan charges plus message charges.

So, their approximate bill will be :
=>
=> y = 26070
Therefore, bill will be $26070.
Your vertex is (8,7)
First find the x intercept
-2/2a
X = 16/2
X = 8
Substitute the value x and solve for y
Youd get 7
Hence
(8,7)
